  * Abstract implementation of a list.
  *
  * `ListBase` can be used as a base class for implementing the `List` interface.
  *
  * All operations are defined in terms of `length`, `operator[]`,
  * `operator[]=` and `length=`, which need to be implemented.
  *
  * *NOTICE*: Forwarding just these four operations to a normal growable [List]
